Segmentation Rules eXchange or (SRX) is an XML-based standard that was maintained by Localization Industry Standards Association, until it became insolvent in 2011 and then GALA.
SRX provides a common way to describe how to segment text for translation and other language-related processes. It was created when it was realized that TMX leverage is lower than expected in certain instances due to differences in how tools segment text. SRX is intended to enhance the TMX standard so that translation memory (TM) data that is exchanged between applications can be used more effectively. Having the segmentation rules that were used when a TM was created will increase the leverage that can be achieved when deploying the TM data.
Implementation Difficulties: SRX make use of the ICU Regular Expression syntax, but not all programming languages support all ICU expressions, making implementing SRX in some languages difficult or impossible. Java is an example of this.
